Question

Plants I

1. Be able to recognize specimens of Bryophytes and Pterophytes

2. Be able to distinguish between the sporophyte and the gametophyte on these plants

3. Know the difference between antheridia and archegonia

4. Understand what spores are

5. Be able to label the basic parts of the alternation of generations of these groups

all of these are question

i don't know how to answer this to you. but this is lab questions. or leave #5 out

Answer 1

1 bryophytes eg -liverot,mosses

​​​​​​

Pteridophytes

2 sporophyte and gametophyte of bryophytes

Sporophyte and gametophyte of pteridophyte

3 differences between Antheridia and archegonia

4 spores

Spores are produced during the life cycle of lower plants are cryptogams comprising algae ,fungi etc. ​​​​​​ They are most conspicuous in the non-seed-bearing plants, including liverworts, hornworts, mosses, and ferns. In these lower plants, as in fungi, the spores function much like seeds. In general, the parent plant sheds the spores locally; the spore-generating organs are frequently located on the undersides of leaves. Lower plants produce single celled spore.Bacteria, fungi and lower plants survive in adverse conditions through formation of thick walled spores. Algae form resting spore or akinetes which are thick walled spores and store food material. In fungi, thick walled perennating spores called chlamydospores are formed.

5 alternation of generation in bryophytes
