Plant reproduction
-
Seed dispersal in plants
On water- some seeds fall into water bodies, that transport them to a different place. Eg- coconut
-
Bursting- some plants, once seeds are produced, burst out on the tiniest reaction, propelling their seeds to different places with such force
By living organisms- organisms, once eating a fruit, dispose of the seeds to different places, where they grow
Asexual reproduction
A mode of reproduction that only involves one parent. The offspring are genetic clones of the parent.
-
Types
Binary fission- where a cell rapidly increases in size and divides itself into two daughter cells under favorable conditions. Nucleus and cytoplasm are divided equally
Multiple fission- where a cell divides into multiple daughter cells in unfavorable conditions. Forms a cyst to protect from unfavorable conditions
Budding- where a mature cell produces bud-like projections from it, which further detaches to form new cells
Fragmentation- when a mature cell cuts itself into two or more parts. Each part grows into an individual cell
Spore formation- where a plant cell divides into spores and are released into the environment. Or when Rhizopus is formed in bread mold. Hyphae and sporangia are part of Rhizopus. Sporangia contains spores and releases them during favorable conditions
-
Vegetative Propagation
This is a mode of asexual reproduction in plants where a part of a plant is modified in such a way that it is able to grow into new plants
-
Advantages- it takes lesser time and the offspring produced are genetically same as the parent plant
-
Types of flowers
Unisexual- plants with either the female reproductive or the male reproductive organs. Male gametes are produced in pollen and female gametes are produced in ovules.
-
Sexual reproduction
When two individuals of opposite gender mate together and produce male and female gametes that fuse to produce zygotes.
-
Reproduction
It is an organism's ability to produce offspring of their own. These offspring may be genetically similar to the parent or of the same species
