Study carerully Specimens H, J, Kand L and use them to answer the following question:
(a) Make a drawing 8-10cm long of the longitudinal section of specimen H and label fully.
(ii) What type of fruit is specimen H?
(ii) State two other examples of the type of fruit to wnich specimen H belongs.
(iv) Is specimen H a true fruit or a false fruit?
(v) Give one reason for your answer in a(iv) above.
(vi) State the food classes present in specimen H.
(b)(i) State one(1) feature common to specimens J, K and L.
(ii) State two observable characteristic features each of specimens J, K and L.
(iii) State the mode of vegetative propagation of specimens K and L.
(C) State the biological significance of specimens K.
(ii) (v) Fruit type: Berry
(iii) Examples: Guava, pepper, garden egg. pawpaw, oranges, citrus fruit.
(iv) True fruit.
(v) It is developed from fertilized ovary.
(vi) Classes of food in Specimen H/ Tomato fruit: - Vitamins. Minerals -Salts - Cabohydrates - Water
(O0) common feature: They are all leaves/ they all have leaves.
(ii) J/Gloriosa: - Tip of midrib/leaf into a tendril.
- Leaves are sessile/no petiole/leaf stalk, - Leaf with parallel veins.
J/Pumpkin: Tendril at tne axile of the leaf. -Hairy leaf
- Net/recticulate venation.
Specimen K/Brvophvllum: Leaf bear buds at notches of margin.
- Leaf is succulent/fleshy/swollen. - Leaf has waxy surface.
Specimen L/Onion Bulb: - Presence of swollen leaf bases (witn reserve food).
- Stem reduced to disc like structure, -Terminal and axilary buds present.
- Presence of leaf scales -Adventitious roots present.
(iii) Mode of vegetative propagation of K and L:
K/Bryophylum: Sprouting of adventitous buds; at margins of leaves.
Specimen L/Onion bulb: Terminal/lateral buds, sprout of new aerial shoots.
(c) Biological significance of K: Vegetative reproduction. -Storage organ (store water, mineral salts, etc).
characteristics of parent plant are preserved. - Can photosynthesize.
