2
Peritrophic membrance is formed around the food in the 1). Mouth2). Crop3). Mesenteron4). Colon
The food bolus in the mesenteron is enveloped by a porous, mesh like membrane called peritrophic membrane which is secreted by the glandular cells of anterior part of the mesenteron. Peritrophic membrane protects the wall of mesenteron from hard food particles.

1) Generative fertilization 2) Syngamy 3) Vegetative fertilization 4) Both (a) and (b)
SOLUTION Fertilization otherwise called generative treatment, insemination, fertilization, fecundation, syngamy, and impregnation, is the combination of gametes to start the improvement of another individual life form.
8 Morphology of Flowering Plants
A plant in which secondary rachii are modified into phyllodes is 1) Acacia melanoxylon 2) Opuntia dillenii 3) Parkinsonia aculeata 4) Asparagus racemosus
Solution
Rachis is modified into a leafy structure called Phyllode. Phyllode is a modified rachis or petiole of leaf. It is green in colour and can perform photosynthesis.

10
The series of mitotic divisions that occurs directly after a zygote is formed is known as
Cleavage is a series of mitotic cell divisions where there is no increase in cell size, just cell numbers. This is how organisms grow.
Fertilization is the union of sperm and egg to make a zygote. Meiosis is the process whereby the sperm and egg form. Parthenogenesis is a unique process whereby unfertilized eggs develop into new organisms, and is commonly found among insects.
