|
|
Features of animal kingdom: |
-have a nucleus, no cell walls or chloroplasts -feed on organic substances made by other living organisms |
|
|
Features of the plant kingdom: |
-have a nucleus and cell walls made of cellulose, often contain chloroplasts - feed by photosynthesis - may have roots, stems and leaves |
|
|
Features of the fungi kingdom: |
- main body is made up of hyphae - usually multicellular, but some like yeast are unicellular - have nuclei and cell walls, but the walls aren't made of cellulose - do not have chlorophyll - feed by digesting waste organic material and absorbing it into their cells |
|
|
Features of the protoctist kingdom: |
- they are multicellular or unicellular - have a nucleus and may or may not have a cell wall and chloroplasts - some feed by photosynthesis and some feed on organic substances made by other organisms |
|
|
Features of the prokaryote kingdom: |
- usually unicellular - no nucleus - have cell walls not made of cellulose - no mitochondria -have a circular loop of DNA, which is free in the cytoplasm - often have plasmids |

Common features of arthropods: |
- jointed legs - exoskeleton - segmented body |
|
|
Features of monocotyledons (monocots): |
- have one cotyledon in their seeds - their roots grow out directly from the stem - their leaves have parallel veins - have flower parts in multiples of three - have vascular bundles in the stem, arranged randomly |
|
|
Features of dicotyledons (dicots): |
- have seeds with two cotyledons - usually have a main root with side roots coming out from it - leaves have a network of veins - have flower parts in multiples of four or five - have vascular bundles in the stem, arranged in a ring |
|
|
cell membrane |
a very thin, partially permeable layer surrounding the cytoplasm of every cell ; it controls what enters and leaves the cell |
|
|
cell wall |
a tough layer outside the cell membrane ; found in cells of plants, fungi and bacteri |
