Chapter 1 Unit Test

what is Tissue

• cells perform specific jobs

• groups of similar cells that do a specific job

• different tissues working together

Answer explanation

Tissue is defined as groups of similar cells that do a specific job, making this choice correct. The other options describe cells or multiple tissues, but do not accurately define what a tissue is.

what is Specialization

• cells perform specific jobs

• group of similar cells that do a specific job

• different tissues working together

Answer explanation

Specialization refers to the process where cells perform specific jobs, allowing for greater efficiency and functionality within an organism. This makes 'cells perform specific jobs' the correct choice.

Mitochondria

• “mighty” power house

• Control what comes into and out of a cell

• Captures energy from the sunlight

Answer explanation

Mitochondria are often referred to as the "mighty" power house of the cell because they generate ATP, the energy currency, through cellular respiration, making them essential for energy production.

The three domains are:

• Bacteria, Archaea, Eukarya

• Bacteria, Archaea, Nucleus

• Bacteria, Cell Wall, Eukarya

Answer explanation

The three domains of life are Bacteria, Archaea, and Eukarya. This classification reflects the fundamental differences in cellular organization and genetics among these groups, making the first option the correct answer.

What is the correct order of levels of organizations?

• cell membrane, cytoplasm, nucleus

• specialized cells, tissue, organ, organ systems

• tissues, organs, specialized cells

Answer explanation

The correct order of levels of organization is specialized cells, tissue, organ, and organ systems. This hierarchy shows how cells combine to form tissues, which then form organs, and finally integrate into organ systems.

True or False. Eukarya include rocks.

• True

• False

Answer explanation

False. Eukarya refers to a domain of life that includes organisms with eukaryotic cells, such as plants, animals, and fungi. Rocks are non-living, inorganic materials and do not belong to any biological classification.

What is the function of chloroplasts in plant cells?

• Store nutrients

• Photosynthesis

• Protect the cell

Answer explanation

Chloroplasts are essential for photosynthesis, the process by which plants convert sunlight into energy. They contain chlorophyll, which captures light energy, making 'Photosynthesis' the correct function of chloroplasts.

True or False. The cell wall is found in both plant and animal cells.

• True

• False

Answer explanation

False. The cell wall is present in plant cells, providing structure and support, but it is absent in animal cells, which have only a cell membrane.

I am the outer most layer of an animal cell. What am I?

• cell wall
• nucleus
• cell membrane 
• cell skin

Which part of the cell is responsible for packaging and distributing proteins?

• Nucleus

• Ribosome

• Golgi Apparatus

• Lysosome
