In the nucleus are a number of thread-like structures called chromosomes. Each cell has fixed number of chromosomes.
Each chromosome is made up of two parallel strands called chromatids each pair of chromatid is connected atone point by a structure called centromere.
Chromosomes are present in the nucleus all the time, but only become visible when viewed under a microscope during cell division.
Chromosomes occur in pairs in the body cells and each pair has a characteristic length. The member of each pair is called a homologous chromosome. This means that they look alike in appearance although their genetic composition may be different.
Along the length of the chromosomes is a series of structures called genes. They are too small to be seen even under a powerful microscope. Genes determine the characteristics of the cell and its progeny.
The sequence of events leading to cell division in plants and animals is basically the same.
There are two types of cell division namely mitosis and meiosis.
pls mark the brainlist
Egg cell + Sperm cell = Zygote -> Embryo -> Fetus
Fertilization
Animal sexual reproduction
Pollination
Ovum + Pollen = Zygote -> Embryo -> Fruit/seed
Fertilization Fertilized egg
Plant sexual reproduction
