Answer:
1)A flower can be defined as the reproductive unit of any angiosperms. Flowers carry out sexual reproduction in angiosperms. A typical flower is generally an attractively modified stem with a condensed axis. A flower has four different parts, they are - calyx, corolla, androecium, and gynoecium.
2)Algae are classified into three classes. They are Chlorophyceae, Phaeophyceae and Rhodophyceae.
3)a)Lumbricina
b)Anura
4)Gap junctions perform cementing function to keep the neighbouring cells together.
5)The basic unit of the nervous system is a nerve cell, or neuron.
6)Collagen is a fibrous protein whichis the major structural component of the bone matrix.
7)In an animal cell, cytokinesis is achieved by the appearance of a furrow in the plasma membrane. The furrow gradually deepens and ultimately joins in the centre dividing the cell cytoplasm into two. Plant cells however, are enclosed by a relatively inexte’nsible cell wall, therefore they undergo cytokinesis by a different mechanism. In plant cells, wall formation starts in the centre of the cell and grows outward to meet the existing lateral walls. The formation of the new cell wall begins with the formation of a simple precursor, called the cell-plate that represents the middle lamella between the walls of two adjacent cells.
8)Oxygen is the final acceptor of electrons because being a highly electronegative element it pulls the electrons and with the hydrogen molecule it forms water molecule and thus terminates the aerobic respiration.
9)2,4-dichlorophenoxyacetic acid
10)A heterocyst is a differentiated cyanobacterial cell that carries out nitrogen fixation. The heterocysts function as the sites for nitrogen fixation under aerobic conditions. They are formed in response to a lack of fixed nitrogen (NH4 or NO3).
11)The lateral line system allows the fish to determine the direction and rate of water movement. The fish can then gain a sense of its own movement, that of nearby predators or prey.
12)Glycine
13)It maintains the proton gradient on the two sides of the membrane.
14) NO IDEA
