(i)Movement
(ii)nutrition
(iii)respiration

(1aii)
(i)Movement is the ability of an organism to move its own whole body or part of its body from one place to another
(ii)nutrition is defined as the ability of living
organisms to feed. This is essential for
growth,respiration and production.
(iii)respiration is defined as the exchange of
gases between organisms take in oxygen and breathe out carbon dioxide.

(1b)
Pls Put this in a tabular form.

PLANTS:
(i)movement are restricted.
(ii)the cell are rigid.
(iii)they manufacture food with chlorophyll.
(iv)growth is not limited.

ANIMAL:
(i) they move in different ways
(ii) the cells are flexible
(iii)they depend on already made food
(iv) growth gradually comes to a stand still

(1ci)
Euglena

(1cii)
Animal features possess by euglena are;
(i)possession of flagellum for locomotion
(ii)possession of pellicle
(iii)possession of eye spot for response to light
(iv)presence of contractile vacuole for excretion
Plant features posses by euglena are;
(i)possession of chloroplast for photosynthesis
(ii)possession of pyrenoid
(iii) possession of cellwall,

(3a)
i.Biosphere is the zone of the earth occupied by living organisms. it is a layer of life which exists on the earth surface
ii. Habitat is defined as an area occupied by a biotic community i.e. habitat is any environment. in which an organism lives naturally e.g the habitat of the fish is water

(3b)Example of a canivorous plant is sundew
that possesses leaves capable of forming an
organ to trap and digest insects. the upper
surface of the leaf has a number of glandular or tentacles. The leaf surface is sticky as a result of disgestive gland in the plant the ends of the tentacles secrete enzymes capable of digesting insects caught the presence of an insect on the
leaf stimulates the leaf to fold over and turn all the tentacles inward.

(3c) (i) It helps to prevent overcrowding of plants

(ii) It results in colonization of new areas with new plants
(iii) it prevents diseases from spreading among plants species

(3d) Six Methods of Conserving soil
-By applying manure
-By avoiding bush burning
-Preventing over grazing
-Preventing Desforestation
-Adoption of better farming practise e.g crop
rotation
-BY avoiding soil erosion

(6a)
- In search for habitat
- In search for mates
- In search for food
- In search for water
-In search for favourable climatic bundles

(6b)
- Epidermes: encloses the vasccular bundles
- Phloem: Transport manufactured food in plant
- Sclerenchyma: It gives the plant resilence
against strong wind

(6c)
i. Parasitic plant: Striga and mistletoe
ii.Saprophytes: Mushroom and fungi

(6d)
i. They posses semi-permeable membrane
ii. They posses bouyant roots

(6e)
