Define sexual reproduction. Give the names of two animals which reproduce sexually. What are seeds? What is meant by germination? What are the conditions required for the germination of seeds? Define pollination.
Understand the Problem
The question is asking for a brief explanation of several topics related to sexual reproduction, seeds, germination, and pollination. Each sub-question requires a concise definition or example.
Answer
a. Sexual reproduction involves fusion of gametes. b. Humans, lions. c. Seeds contain an embryo. d. Germination is seed growth. e. Conditions: water, temperature, oxygen. f. Pollination is pollen transfer.
a. Sexual reproduction is the process in which two gametes, usually from two different individuals, join to form an offspring.
b. Two animals that reproduce sexually are humans and lions.
c. Seeds are structures produced by plants after fertilization, containing an embryo and stored food.
d. Germination is the process by which a seed develops into a new plant.
e. Conditions required for germination include water, suitable temperature, and oxygen.
f. Pollination is the transfer of pollen from the male part of a flower to the female part.

More Information
Sexual reproduction ensures genetic diversity, which is advantageous for adaptation. Germination can be inhibited by insufficient water, unsuitable temperatures, or lack of oxygen.
Tips
Common mistakes include not understanding the role of gametes in sexual reproduction and confusing pollination with fertilization.
