What is asexual (vegetative) plant propagation?1 / 10
Asexual propagation is growing a brand-new plant from a piece of a parent plant — a stem, root, or leaf — instead of from a seed. No pollen, egg cell, or fertilization is involved.
World Biomes at a Glance A biome is a large region defined by its climate — how much rain falls and how hot or cold it gets. Each biome is home to plants and animals with adaptations suited to that climate. The table below compares five maj
What is the main role of cytokinins in plant growth?1 / 9
Cytokinins are plant hormones that promote cell division. Wherever cytokinin levels are high, plant tissue is stimulated to actively produce new cells, which is essential for growth in root tips, shoot tips, and developing fruit.
An Introduction to Biotechnology: Cloning and GMOs Biotechnology is any use of living things, or the tools inside them, to solve a practical problem. Two of the most talked-about examples are cloning — making a genetic copy of an organism —

The Neuron: The Nervous System's Basic Unit The nervous system is built from specialised cells called neurons, each adapted to receive, carry, and pass on electrical nerve impulses. A neuron has a cell body, branching dendrites that receive
The integumentary system The integumentary system consists of the skin and its accessory structures — hair, nails, and glands. It is the body's largest organ system, forming a flexible, self-repairing barrier between the internal body and t
Cellular Respiration: Releasing Energy From Food Every living cell needs energy to survive — energy to grow, move, and repair itself. Cells get that energy from food through a process called cellular respiration. The simple word equation fo
