Characteristics of plantae

Answer 1

Characteristics of Thallophyta : 1) They are found in moist or wet places.

2) They are autotrophic ,i.e, manufacture their own food. Reserve food is generally

Starch.

3) They have a cellulose cell wall around their cells.

4) Mechanical & conducting elements are absent.

5) Sex organs are simple, single celled, there is no embryo formation after fertilization.

Answer 2

1-tracheophytes have conducting and vascular tissues

2-all of them have well developed root , stem and leaves

3-they are very greatly in height from miniature to giant size

4-they all show alternation of generation

5-sporophyte generation of it is totally independent

6-gametophyte generation may be vary small, short lived and totally depend on sporophyte

7-the zygote form into well-developed embryo

Answer 3

Tracheophytes have roots, stems and leaves. Trees, shrubs, grains, flowers, grasses etc. are considered tracheophytes. Tracheophytes utilize a vascular system for absorption of food, water and metabolism. There are nine divisions or phyla of tracheophytes, divided into three major groups according to their reproduction method:

Psilopsid or seedless

Gymnosperm or non-flowering

Angiosperm or flowering

Answer 4

Lycophyta are distinct in that they only have one vein in each leaf, making them microphylls. They use spores for reproduction and produce highly flammable spores, which are used as an ingredient for some fireworks.

Answer 5

Tracheophyta are vascular plants. These are also known as trees. They must have xylem, which conduct water and minerals throughout them.

Answer 6

Angiospermophyta have flowers as well as ovules in ovaries. These plants produce seeds that have hard coats in fruits.

Answer 7

Bryophytas are non-vascular and they have no roots and only simple leaves and stems. These plants produce spores in capsule.

Answer 8

They have no root,stem and leaves.

They develop pollen grains

They develop flowers and fruits

They have vascular system
