Examine a few flowers of any cucurbit plant and try to identify the staminate and pistillate flowers. Do you know any other plant that bears unisexual flowers?
What is a cucurbit plant? A cucurbit plant is a type of vine that grows in warm climates. The most common types are watermelons, cantaloupes, and pumpkins. Cucurbit plants have large leaves and tendrils that help them cling to supports ...
What is a bisexual flower? Collect five bisexual flowers from your neighborhood and write their scientific names.
Fertilization in flowers occurs when the pollen from the stamen (male organ) of a flower is transferred to the pistil (female organ) of another flower. The pollen contains the male genetic material, and the pistil contains the female genetic material. ...
Describe the post-fertilization changes in a flower
Fertilization in flowers occurs when the pollen from the stamen is transferred to the pistil. The pollen contains the male chromosomes, and the pistil contains the female chromosomes. When they combine, fertilization occurs and seed is formed. During fertilization, the ...
Differentiate between Gametogenesis and Embryogenesis
What is Gametogenesis? Gametogenesis is the process of producing gametes, which are cells that unite to produce a new organism. In males, gametogenesis occurs in the testes and results in the production of sperm. In females, gametogenesis takes place in ...
Why are offsprings of oviparous animals at a greater risk as compared to offsprings of viviparous animals?
What are Oviparous animals? Oviparous animals are those that lay eggs. The eggs are then fertilized by the male and develop into offspring outside of the mother’s body. Some common oviparous animals include fish, amphibians, reptiles, and birds. What are ...
Differentiate between a zoospore and a zygote.
What is a Zygote? A zygote is an embryo that results from the fusion of two gametes (sperm and egg). It is the earliest stage of development in a multicellular organism. What is Zoospore? Zoospore is a term used in ...
Define external fertilization. Mention its disadvantages.
Definition: External fertilization is the process of fertilizing an egg outside of a female’s body. This is done by injecting sperm into the water surrounding an egg that has been removed from a female fish or by inserting a needle ...

Explain why meiosis and gametogenesis are always interlinked?
What is Gametogenesis? Gametogenesis is the process by which sex cells, or gametes, are produced in an organism. Gametes are haploid cells that contain one set of chromosomes. In humans, gametogenesis occurs in the gonads—the testes and ovaries. The process ...
