Discuss with your teacher about.
1. haploid insects and lower plants where cell division occurs, and
2. Some haploid cells in higher plants where cell division does not occur.
1. Male bees, wasps and ants are haploid as they are produced from unfertilized eggs.
2. Synergids and antipodal cells do not divide.
1. Chromosomes are moved to spindle equator.
2. Centromere splits and chromatids separate.
3. Pairing between homologous chromosomes takes place.
4. Crossing over between homologous chromosomes takes place.

Cytokinesis |
Karyokinesis |
|
1.It is a division of cytoplasm into daughter cells. 2. Stages such as prophase, metaphase, anaphase, and telophase are not present in cytokinesis. |
1. It is division of nucleus into daughter nuclei 2. It is divided into four stages: prophase, metaphase, anaphase, and telophase |
1. Synapsis
2. Bivalent
3. Chiasmata.
Draw diagrams to illustrate your answer.
2. Bivalent : A pair of homologous chromosomes is called bivalent.
3. Chiasmata : It is point in a tetrad where crossing over occurs.
