Question

Fill in the boxes given in fig with appropriate characteristics plant

Answer 1

The explanation for the correct option:

(A) Thallophyte

1. Formerly classified as a primary division (Thallophyte) of the plant kingdom.
2. Thallophyte of a group of plants or plantlike organisms (such as algae and fungi) that lack differentiated stems, leaves, and roots
3. For example, Ulothrix, Cladophora, Chara, Spirogyra, and Ulva.

(B) Bryophyte

1. Bryophytes are also called amphibians of the plant kingdom
2. It is thallus-like and prostrate or erects and rhizoids.
3. They lack true roots, stems, or leaves.
4. They have root-like, leaf-like or stem-like structures.
5. They lack vascular tissue.
6. Bryophytes absorb most of their water through above-ground substances.

(C) Pteridophyte

1. They reproduce via spores
2. They have neither seeds nor flowers.
3. They were the precursor to the seed habit considered an important step in evolution.

(D) Phanerogams

1. Phanerogams are divided into gymnosperm and angiosperm.
2. Spermatophyte also known as phanerogam is any plant that produces seeds.
3. Seeds in gymnosperms are not covered and do not produce a flower.
4. Seeds in angiosperm are covered and produce the flower.

(E) Bare naked seed

1. The gymnosperms have naked seeds.
2. In gymnosperms, ovules are not covered by any ovary wall and remain exposed, both before and after fertilization.
3. Since gymnosperms, their seed is not covered do not produce flowers and fruits.
4. Examples are ginkgo and sago palm

(F) Angiosperm

1. The angiosperms are also called flowering plants.
2. Their seeds are enclosed and produce fruits.
3. The dicotyledons and the monocotyledons are two classes of angiosperm
4. Dicotyledon seeds have two cotyledons.
5. Monocotyledons have a single cotyledon seed.

(G) Seed with two cotyledons

1. Seeds with two cotyledons are called dicotyledonous.
2. It leaves have reticulate venation
3. Floral appendages in them are present in multiple four or five.
4. Examples are apples, mango, and roses.

(H) Monocots

1. Seeds with one cotyledon are called monocotyledons
2. In it leaves have parallel venation.
3. Floral appendages in them are present in multiple three.
4. Examples are garlic, onion, and lily.

The final answer:

a) the Thallophyte plant body is not differentiated

b) Vascular tissue without specialization is present in bryophytes.

c) Pteridophytes do not produce seeds.

d) Phanerogams are also called spermatophytes and have seeds

e) Bare naked seeds present in gymnosperm

f) Angiosperm bears seed inside the fruit.

g) Seed with two cotyledons called dicotyledon

h) Monocots have seeds with one cotyledon.
