Question

3. How do fungi differ from plants? Describe the structure of a mould.
4. Mention the different types of plants included in the kingdom Plantae.
5. What are the different forms of algae?
6. Distinguish between naked-seeded and closed-seeded plants.

Answer 1

Answer:

3. While both are eukaryotic and don't move, plants are autotrophic - making their own energy - and have cell walls made of cellulose, but fungi are heterotrophic - taking in for energy - and have cell walls made of chitin.

4. Kingdom Plantae is broadly composed of four evolutionarily related groups: bryophytes (mosses), (seedless vascular plants), gymnosperms (cone bearing seed plants), and angiosperms (flowering seed plants).

5. Algae And Their Characteristics, Types Of Algae, Ecological Relationships, Factors Limiting The Productivity Of Algae=

1. Euglenophyta (euglenoids) ...

2.Chrysophyta (golden-brown algae) ...

3.Pyrrophyta (fire algae) ...

4. Chlorophyta (green algae) ...

5. Rhodophyta (red algae) ...

6. Paeophyta (brown algae) ...

7. Xanthophyta (yellow-green algae)

6. Gymnosperms are seed-bearing vascular plants, such as cycads, ginkgo, yews and conifers, in which the ovules or seeds are not enclosed in an ovary. ... Closed seeded plants: The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary.

Hope the answer is correct.

Answer 2

Fungi and plants differ in many ways

First, plants use sunlight as an energy source and a carbon dioxide as a sole carbon source in a process called photosynthesis. Fungi, like animals, use premade organic compunds as both carbon and energy source. Hence, fungi do not have chloroplasts nor chlorophyll.

Although both fungi and plant cells have cell wall, it is quite different in structure and composition. While plant cell wall is composed of cellulose, cell wall in fungi is made from chitin and beta-glucan mollecules.

Fungal cells grow differently than plant cells. They grow as filamentous structutres called hyphae which extend at their tips. Similar structures in some algae grow by repeated cellular division. Unlike plants, fungi do not form specific tissues, nor organs. Instead, branched network of hyphae forms mycelium in most fungal species.

Fungi store glycogen as energy reserve, as animals do. Plants store starch.

There are major differencies in fungal and plant reproduction. For example, fungi never produce fruits nor seeds.

In the end, fungi and plants have different DNA sequences. Fungal DNA is more similar to those of animals than to plants.
