What is Variation?
Noticeable change in 2 different species
It is the copying during reproduction is important for maintaining the body designs of different organisms to survive in the existing environment.
It refers to the visible difference between two individuals or among a group of individuals or species.
The number of chromosomes in parents and offsprings of a particular species remains constant due to:
(a) Doubling of chromosomes after zygote formation
(b) Halving of chromosomes during gamete formation
(c) Doubling of chromosomes after gamete formation
(d) Halving of chromosomes after gamete formation

(a) Fertilisation
(b) Fission
(c) Tissue culture
(d) Fragmentation
All of these animals are pollinators EXPECT
Bee
Bird

1. A feature of reproduction common to amoeba, spirogyra and yeast is
They reproduce asexually
They are unicellular
They reproduce sexually
They are multicellular
1. Vegetative propagation refers to formation of new plants from-
Stem, root, flower
Stem, root, leaves
Stem, fruits, flower
Stem, leaves, flower
New plants grow from pieces or cuttings of parent plants
Budding
REGENERATION
MITOSIS
VEGETATIVE PROPAGATION
The process by which an organism produces others of its same kind.
Reproduction
Sexual Reproduction
Asexual Reproduction
Budding
A small copy of parent organism grows on parent body and breaks off as it gets larger
MITOSIS
FISSION
Budding
REGENERATION
Require two organisms, where two sex cells come together to reproduce an offspring.
Fission
Sexual Reproduction
Budding
Asexual Reproduction
Organism grows new parts to replace broken-off ones
REGENERATION
Budding
Mitosis
Fission
These are types of sexual Reproduction:
Mitosis
Fission
Regeneration
Budding
Vegetative Propagation
True
False
This occurs in Bacteria cells which are Prokaryotes (don’t have a nucleus)
Mitosis
VEGETATIVE PROPAGATION
FISSION
Budding
These are types of asexual Reproduction:
