Q
what are the common feature shown by plant eukaryotic organisms ?
A
- multicellular
- contain chloroplasts
- can photosynthesise
- cellulose cell walls
- store carbohydrates as starch or sucrose
2
Q
what are some flowering plant examples ?
A
- cereals such as maize
- herbaceous legumes such as peas and beans
3
Q
what are the common features shown by an animal eukaryotic organism ?
A
- multicellular
- no chloroplasts so cannot photosynthesise
- no cells wall
- usually have nervous co-ordination
- are able to move
- often store carbohydrates as glycogen
4
Q
what are some animal examples ?
A
- mammals such as humans
- insects such as mosquitos and houseflies
5
Q
what are the common functions shown by a fungus eukaryotic organism ?
A
- unable to photosynthesise
- body organised into mycelium made from thread like structures called hyphae
- hyphae contain many nuclei
- can be single celled
- cell walls made of chitin
- store carbohydrates as glycogen
6
Q
what type of nutrition do fungi use ?
A
saprotrophic nutrition
7
Q
what is saprotrophic nutrition ?
A
fed by extracellular secretion of digestive enzymes into food material and absorption of the organic products
8
Q
what are some fungi examples ?
A
- with hyphal structure is Mucor
- single celled is Yeast
9
Q
what are the common functions shown by a protoctist eukaryotic organism ?
A
- microscopic
- single celled
10
Q
what are some protoctist examples ?
A
- Amobea (live in ponds and similar to animal cells)
- Chlorella (have chloroplasts and similar to plant cells)
- Plasmodium (pathogenic and cause malaria)
