• Define species
• Compare and contrast sexual and asexual reproduction

Mahi Tuatahi

Think, pair and share:

• recall MRS C GREN,
• define “species”,
• discuss the importance of reproduction & the two ways to do it,
• and think of any advantages/disadvantages

MRS C GREN: Movement, Respiration, Sensitivity, Circulation, Growth, Reproduction, Excretion, Nutrition

Species: A group of organisms that can produce viable offspring

Reproduction

There are two ways to reproduce: sexual reproduction and asexual reproduction.

Sexual Reproduction

• Takes a lot of energy (effort)
• Involves sex cells (gametes)
• Greater genetic variation

What does sexual reproduction?

Any animal that you can think of that has different sexes and some flowers and plants.

Asexual Reproduction

• Involves a single organism
• Produces clones (very little variation)
• Requires less energy

What does asexual reproduction?

Some plants, bacteria, some insects

Does anything do both?

Yes, aphids, slime moulds, sea anemones and some starfish are tauria of organisms that can do both sexual and asexual reproduction.
