Growth in Organisms: Understanding Cell Division and Differentiation in Animals and Plants

The video explores the concept of growth in biology, focusing on animals and plants. It explains how growth in animals involves cell division and differentiation, while plants also experience cell elongation. The video also covers how growth can be monitored using measurements and percentile charts. Finally, it recaps the importance of specialized cells and the use of percentile charts in tracking growth.

What is the biological definition of growth?

• A temporary increase in cell number

• A decrease in cell number

• A permanent increase in the number and/or size of cells

• A temporary increase in cell size

How do animal cells primarily increase in number?

• Through binary fission

• Through budding

• Through mitosis

• Through meiosis

What is the process called when a less specialized cell becomes more specialized?

• Mitosis

• Differentiation

• Elongation

• Photosynthesis

Where is meristem tissue found in plants?

• At the tips of growing roots and shoots

• In the fruit

• In the leaves

• In the flowers

What unique growth process occurs in plant cells but not in animal cells?

• Mitosis

• Elongation

• Photosynthesis

• Differentiation

What is a percentile chart used for?

• To track the growth trend of an individual over time

• To determine the lifespan of an organism

• To measure the height of plants

• To calculate the average weight of animals

What does it mean if a baby's growth points closely follow a percentile line on a chart?

• The baby is growing abnormally

• The baby is losing weight

• The baby is not growing

• The baby is growing normally
