Which two statements are part of the modern cell theory?

• All organisms are made up of cells

• The Cell saga was the best Dragon Ball Z arc

• All cells contain genetic material in the nucleus

• Cells are the basic units of life

Which data set correctly identifies the structure and function of the animal cell organelles?

• vacuole: storage of food, nutrients, or waste

  cytoplasm: fluid that fills a cell

  cell membrane: controls the materials entering and leaving the cell

• vacuole: storage of food, nutrients, or waste

  nucleus: protection and support

  chloroplast: site of photosynthesis

• mitochondrion: breaks down food into usable form

  cell wall: protects and supports

  nucleus: controls eating, movement, reproduction

• cytoplasm: fluid that fills a cell

  mitochondrion: breaks down sugars and nutrients

  vacuole: protection and support

Identify the two products of photosynthesis.

• Glucose (C6H12O6)

• Water (6H2O)

• Oxygen (6O2)

• Pretty flowers

When a plant lacks water, the vacuole shrinks causing the plant to wilt. This is a response of what internal stimuli?

• lower rate of photosynthesis in the roots

• increased amounts of glucose stored in the leaves

• decreased water pressure within the plant cells

• lack of nutrients carried by water in the plant

Which data set correctly matches the body system with its function?

• -skeletal: enables movement

  -nervous: controls body functions

  -endocrine: regulates hormones

  -muscular: support and protects organs

• -skeletal: supports and protects organs

  -nervous: enables movement

  -endocrine: controls body functions

  -muscular: regulates hormones

• -skeletal: support and protects organs

  -nervous: controls body functions

  -endocrine: regulates homeostasis

  -muscular: enables movement

• -skeletal: enables movement

  -nervous: controls body functions

  -endocrine: supports and protects organs

  -muscular: regulates homeostasis

According to cell theory, which of these statements is NOT correct?

• An amoeba is called living even though it is single-celled.

• An amoeba cell can perform all processes necessary for life.

• An amoeba cell can divide to form two daughter cells.

• A water droplet from the pond can give rise to an amoeba cell.

Students learned that the job of one organelle in a cell is to filter out cellular wastes, toxins, and excess water or nutrients. Which body system has this function?

• Excretory System

• Muscular System

• Respiratory System

• Nintendo Entertainment System

Which body systems work together to provide oxygen to all cells within a human organism?

• Digestive and Respiratory systems

• Circulatory and Respiratory systems

• Endocrine and Excretory systems

• Low Pressure and High Pressure systems

• chemical/physical

• chemical/chemical

• physical/chemical
