John was reading a chapter on different parts of a green plant. His mother asked him about the functions of roots. He replied that roots are meant for anchorage and absorbing water and minerals from soil. Then mother showed him carrot, radish and turnip and asked him about the additional functions that the roots perform. John was surprised to find that roots in some plants change their shape and structure and become modified to perform additional functions like support, storage of food and respiration.

(1). Carrot is a
(a) Tap root (b) Fibrous root (c) Adventitious root (d) Stilt root.

(2). Hanging structures that support a banyan are
(a) Prop (b) Tuber (c) Rhizome (d) Stilt

(3). Supporting structures coming out of the lower nodes of the stems of maize and sugarcane are
(a) Stilt (b) Tendrils (c) Runner (d) Prop

(4). Which function is performed by the modified roots of Asparagus?
(a) Storage (b) Support (c) Respiration (d) Transpiration.

(5). Pneumatophores are found in
(a) Rhizophora (b) Asparagus (c) Sugarcane (d) Maize.

Alex used to go to vegetable market with his grandfather, a retired biology teacher. Grandfather told Alex that brinjal, chillies and tomato belong to the same family of plants and asked him to find out the similarity in these plants. Alex found that it's a large family, commonly called as the ' potato family'. Plants belonging to this family are mostly herbs, shrubs and rarely small trees. Many plants belonging to this family are source of food, spice, medicine, fumigatory, and ornamental.

(1).The name of this family is
(a) Solanaceae  (b) Fabaceae  (c) Liliaceae  (d) Brassica ear.

(2). Fruits of this family are known as
(a) Berry or capsule  (b) Legume  (c) Endosperm  (d) Cotyledon.

(3). Aestivation in calyx and corolla of this family is
(a) Valvate  (b) Imbricate  (c) Twisted  (d) Vexillary.

(4). Stamens of the flowers belonging to this family are mostly attached with petals.This condition is known as
(a) Epipetalous  (b) Epiphyllous  (c) Polyandrous  (d) Monoadelphous

(5). Medicinal plants belonging to this family are
(a) Belladonna, Ashwagandha
(b) Aloe, Asparagus
(c) Tobacco, Petunia
(d) Muliathi, Spice.

How do the various leaf modifications help plants?

Take one flower each of the families Fabaceae and Solanaceae and write its semi-technical description. Also draw their floral diagram after studying them.

Describe the arrangement of floral members in relation to their insertion on thalamus.

Describe the various types of placentations found in flowering plants.

What is meant by modification of root? What type of modification of root is found in the:

1. Banyan tree.
2. Turnip.
3. Mangrove trees.
