Arrange the following terms in the correct developmental sequence: Pollen grain, sporogenous tissue, microspore tetrad, pollen mother cell, male gametes.

Study carefully the following stages of life cycle of malarial parasite i.e., plasmodium. Arrange these stages in the correct sequence and select the correct answer 1) Sporozoites leave the blood stream and enter the liver cells of man 2) Sporozoites present in the salivary glands of female Anopheles mosquito are injected into the blood stream of man 3) The parasite reproduces asexually in RBCs, resulting in bursting of RBCs and causing the cycles of fever, released parasites infect new RBCS 4) The parasite reproduces asexually in liver cells, ultimately causing the rupturing of cells 5) Two types of gametocytes i.e., microgametocytes and macrogametocytes develop in the RBCs. 6) Female Anopheles mosquito takes up the gametophytes with blood meal of an infected person ) mature infective stage of the parasite i.e., sporozoites migrate to the mosquito's salivary glands 8) Fertilization and development stages of the parasite takes place in crop of mosquito

Microspores of the following plants are also called as pollen grains

In flowering plants, a mature male gametophyte is derived from a pollen mother cell by

If there are 40 pollen mother cells in anther, what will be the number of pollen grains?

What is the function of the two male gametes produced by each pollen grain in angiosperms.

An anther has 3600 pollen grains. How many pollen mother cells must have been there to produce them?

An anther has 1200 pollen grains. How many pollen mother cells must have been there to produce them ?

Read the following arrange them in a correct sequence in the activity of Epinephrine on the liver cells A)Formation of cAMP B)Epinephrine binds to membrane receptor C)Activation of phosphorylase D)G protein binds to GTP and activates adenylate cyclase E)Activation of protein kinase A F)Phosphorylation of glycogen to glucose-6 phosphate

In angiosperms how many male gametes are produced by one meiosis in one pollen mother cell (PMC)

Given below are the events that are observed in an artifical hybridization programme. Arrange the in the correct sequential order in which they are. followed in the hybridization programme. a) Re-bagging b) Selection of parent. c) Bagging d) Dusting the pollen on stigma e) Emasculation f) Collection of pollen from male.
