0 of 6 answered

  1. Q1 of 6Easy

    Tissue responsible for plant growth:

    Show answer

    Answer: Meristematic

    Explanation: Meristematic cells divide actively at root and shoot tips to drive growth; permanent tissues such as sclerenchyma and cork have already differentiated and stopped dividing.

  2. Q2 of 6Easy

    Xylem transports:

    Show answer

    Answer: Water and minerals upward

    Explanation: Xylem carries water and minerals upward from roots to shoots; phloem, not xylem, moves sugars, mostly downward from leaves to sink tissues.

  3. Q3 of 6Medium

    Arrange root zones from tip upwards: I-elongation, II-meristematic, III-maturation, IV-root cap.

    Show answer

    Answer: IV → II → I → III

    Explanation: From the tip upward the sequence runs root cap, then the dividing meristematic zone, then the elongation zone, and finally the maturation zone where root hairs appear.

  4. Q4 of 6Medium

    Most common simple tissue in plants:

    Show answer

    Answer: Parenchyma

    Explanation: Parenchyma is the most abundant simple tissue — thin-walled, living, with intercellular spaces for storage and gas exchange; collenchyma and sclerenchyma are specialised for support instead.

  5. Q5 of 6Hard

    Secondary growth in dicot stem is due to:

    Show answer

    Answer: Cambium activity

    Explanation: Secondary growth in girth comes from vascular cambium dividing to add xylem inward and phloem outward; apical meristems only lengthen the plant, they don't widen it.

  6. Q6 of 6Hard

    Assertion: Endodermis is virtually impermeable to water across cell walls. Reason: Suberin deposition forms Casparian strips on radial and tangential walls.

    Show answer

    Answer: Both A and R true; R correct explanation

    Explanation: Suberin deposits forming Casparian strips seal the endodermal cell walls, blocking the apoplast route so water must cross the cell membrane into the symplast — exactly why the reason correctly explains the assertion.

Anatomy of Flowering Plants notes: key concepts (Class 11 Biology)

Anatomy examines the internal tissue organisation of flowering plants. Meristems generate cells that mature into simple and complex permanent tissues; these build the epidermal, ground and vascular tissue systems, whose arrangement distinguishes monocot and dicot organs and drives the secondary growth that thickens stems.

Meristematic tissue
Groups of actively dividing cells. Apical meristems lengthen root and shoot, intercalary ones sit near internodes, and lateral cambia add girth.
Outline of a plant showing where its meristems lie: apical meristem at the tip of the shoot and the tip of the root (shaded), intercalary meristem at the base of an internode just above a leaf, and lateral meristem as thin strips along the sides of the stem. Each is labelled.
Simple permanent tissues
Parenchyma (thin-walled, for storage and photosynthesis), collenchyma (corner-thickened, flexible support) and sclerenchyma (lignified, dead, rigid).
Complex permanent tissues
Xylem (tracheids, vessels, fibres, parenchyma) conducts water and minerals upward; phloem (sieve tubes, companion cells, fibres, parenchyma) moves food.
Xylem & phloem elements
Xylem's tracheids and vessels are dead, lignified conduits; phloem's sieve-tube cells are living but lack a nucleus and rely on companion cells.
Epidermal tissue system
The outermost layer — epidermis with a cuticle, stomata (guard cells) and appendages such as root hairs and trichomes for protection and exchange.
Ground tissue system
All tissues except epidermis and vascular bundles — cortex, pericycle, pith and medullary rays — mostly parenchyma serving storage and support.
Vascular tissue system
Xylem and phloem organised into bundles. Their number, arrangement and whether cambium is present separate dicot from monocot organs.
Vascular bundle types
Conjoint bundles (xylem and phloem on the same radius) are collateral in stems; radial bundles have xylem and phloem on alternate radii in roots.
Three kinds of vascular bundle, coloured xylem red, phloem green, cambium amber. Radial (roots): xylem in four arms and phloem in patches between them, on alternate radii. Conjoint, open (dicot stem): phloem on the outer side and xylem on the inner side of the same radius, with a strip of cambium between them, so the bundle can add secondary tissues. Conjoint, closed (monocot stem): phloem outside and xylem inside on the same radius, with no cambium between them.
Open vs closed bundles
Open bundles keep a cambium and allow secondary growth (dicot stem); closed bundles lack cambium, so no secondary growth occurs (monocot stem).
Dicot vs monocot root
Dicot roots are di- to tetrarch (few xylem groups); monocot roots are polyarch with many. Both have radial bundles; monocot pith is large.
Transverse sections of a dicot root (left) and a monocot root (right). Each has, from outside in, the epidermis, a wide cortex, a ring of endodermis and just inside it the pericycle. Xylem (red) and phloem (green) lie in radial bundles on alternate radii. The dicot root has four xylem arms (tetrarch; dicots have two to four) and almost no pith. The monocot root has many xylem patches (polyarch) round a large central pith.
Dicot vs monocot stem
Dicot stem: bundles in a ring, open, with cambium. Monocot stem: bundles scattered through the ground tissue, closed, without cambium.
Transverse sections of a dicot stem (left) and a monocot stem (right), xylem red, phloem green, cambium amber. Dicot stem: inside the epidermis and cortex, the vascular bundles stand in a single ring round a central pith; each bundle has phloem outside, xylem inside and a strip of cambium between, so it is open. Monocot stem: many smaller bundles lie scattered through the ground tissue, crowded near the edge; each has phloem outside and xylem inside but no cambium, so it is closed. There is no separate cortex and pith.
Dorsiventral vs isobilateral leaf
Dicot (dorsiventral) leaves have palisade above and spongy mesophyll below; monocot (isobilateral) leaves have uniform mesophyll and bulliform cells.
Vertical sections of two leaves. Top, a dicot (dorsiventral) leaf: an upper epidermis; below it a layer of tall, closely packed palisade cells; then loosely arranged, rounded spongy mesophyll cells with air spaces and a vein (xylem above, phloem below, inside a bundle sheath); and a lower epidermis with a stoma. Bottom, a monocot (isobilateral) leaf: large bulliform cells in the upper epidermis, uniform mesophyll not divided into palisade and spongy, a vein, and stomata in both epidermes.
Vascular & cork cambium
In secondary growth the vascular cambium forms secondary xylem (wood) inward and phloem outward, while cork cambium (phellogen) builds the periderm.
Annual rings & bark
Seasonal activity gives spring (early) and autumn (late) wood as annual rings, used to age a tree; all tissues outside the cambium make up bark.
