Plant Systems Review

What are the Products of Cellular Respiration?

Represented by X.

• H₂O + O₂

• H₂O + CO₂

• C₆H₁₂O₆ + O₂

• C₆H₁₂O₆ + CO₂

What cellular process is occurring in the organelle labeled 'B'?

• Photosynthesis

• Cellular respiration

• Chemosynthesis

• Protein synthesis

What cellular process is occurring in the organelle labeled 'A'?

• Photosynthesis

• Cellular respiration

• DNA replication

• Protein synthesis

What statement accurately names and describes the function of the organelle labeled B?

• A mitochondrion produces energy from food to power cellular processes.

• A mitochondrion produces food using radiant energy.

• A chloroplast produces energy from food to power cellular processes.

• A chloroplast produces food using radiant energy.

Which of the following is NOT a growth response of a plant?

• response to light (phototropism)

• response to gravity (gravitotropism)

• response to touch (thigmotropism)

• response to smell (odotropism)

Which statement correctly describes PHOTOTROPISM?

• The plant is growing towards the light source.

• There is not enough water in the soil to keep the plant's stem rigid.

• The plant has been over watered and is beginning to fall.

• Gravity is causing the plant stem to grow toward the ground.

Roots of different plants can be connected by a network of underground fungal extensions called hyphae. These fungi contribute minerals to the plants, and the plants contribute carbohydrates to the fungi.

Part A: Which statement about the transportation of these substances within the plant is true?

• The minerals are transported from the phloem to the xylem in the shoot system.

• The carbohydrates are transported from the shoot system to the fungi by the xylem.

• The minerals are transported from the xylem to the phloem in the roots.

• The carbohydrates are transported to the fungi through the phloem.

Which of the following best describes self fertilization in plants?

• Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches the filament, where the sperm fertilizes the egg.

• Pollen moves from the ovule up through the style and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the egg.

• Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary, where the sperm fertilizes the egg.

• Pollen is released from the stigma and is transferred to the anther. A pollen tube grows down from the anther through the filament and fuses with the ovule, where the sperm fertilizes the egg.

In the images you see a stoma. Stoma help plants with gas exchange and transpiration. Normal conditions the stoma are left open.

What would cause the stoma to close?

• a reduced supply of oxygen

• long periods of rainfall

• high concentrations of glucose

• little available water

What are the 2 products of Photosynthesis?

• Glucose

  C6H12O6

• Phospholipid

• Insulin

• Oxygen

  O2
