Algae
Fungi

Question 3

Characteristics Of Thallophyta

In terms of habitat
In terms of vascular system
In terms of nutrition

Answer 3

They are usually found in moist or wet places.
They lack true roots and vascular tissues; Xylem & Phloem needed to transport water and minerals
They are autotrophic in nature(i.e they manufactured their own food unless a few members like Fungi which are dependent on other sources of food)

Question 4

Characteristics Of Thallophyta

In terms of photosynthetic products
In terms of cell wall
In terms of fertilization

Answer 4

They produce glucose during photosynthesis, a part of which is consumed almost immediately while the remaining glucose is converted into complex compounds called Starch.
Hence, Starch is their food reserve.
They have a cell wall composed of cellulose
They possess simple single celled sex organs and there is no embryo formation after fertilization
