Biology Chapter 2 Test Review

Name the leaf arrangement that has two leaves growing from each node. This arrangement has leaves arranged at right angles to the leaves above and below them, to maximize exposure to the light.

Label the image with the type of leaf arrangement that has only one leaf growing from each node. The leaves are on different sides of the stem.

Label the image with the type of leaf arrangement where three or more leaves grow from each node.

Label the image with the type of leaf pattern where a cluster of leaves grow around the base.

Three types of plant tissues are...

Four types of Structural Tissue

Choose the TWO types of vascular tissue.

Select the THREE kinds of meristematic tissue.

One of the most important types of meristematic tissue is [blank_start]cambium[blank_end] tissue.

The parts of a plant cell that separate its contents from the surrounding environment is called either a cell [blank_start]membrane[blank_end] or a cell [blank_start]wall[blank_end].

The part of a plant cell that controls the cell's activities is called the [blank_start]nucleus[blank_end].

Three types of venation are [blank_start]parallel[blank_end], [blank_start]pinnate[blank_end], and [blank_start]palmate[blank_end].

The structures in a plant cell that carry out photosynthesis are called [blank_start]chloroplasts[blank_end].

[blank_start]Ordinary[blank_end] leaves have petioles; [blank_start]sessile[blank_end] leaves do not.

[blank_start]Simple[blank_end] leaves have only one blade per petiole; [blank_start]compound[blank_end] leaves have more than one blade per petiole.

The purpose of cork tissue is to [blank_start]protect[blank_end] and [blank_start]waterproof[blank_end] the stem.

The purpose of parenchyma tissue is to [blank_start]make[blank_end] and [blank_start]store[blank_end] food.

[blank_start]Xylem[blank_end] tissue transports [blank_start]water[blank_end] and dissolved minerals upwards to the leaves; [blank_start]Phloem[blank_end] transports [blank_start]food[blank_end] manufactured in the leaves downward to the rest of the plant.

The purpose of the leaf's epidermis is to [blank_start]cover[blank_end] and [blank_start]protect[blank_end] the leaf surfaces.

The purpose of vacuoles is to [blank_start]store[blank_end] food materials, fluid substances, and minerals.

This is the process of photosynthesis. The plant uses the energy of the [blank_start]sun[blank_end] to split the [blank_start]water[blank_end] molecules into hydrogen ions and oxygen. The hydrogen ions are combined with [blank_start]carbon dioxide[blank_end] from the air to form [blank_start]glucose[blank_end], a simple sugar.

Choose the 4 factors that affect the rate of photosynthesis:

What causes leaves to turn different colors in autumn?

When the [blank_start]abscission[blank_end] layer forms, the [blank_start]chlorophyll[blank_end] in the leaf begins to deteriorate, allowing other pigments that had previously been [blank_start]hidden[blank_end] by the chlorophyll to become visible.

How do guard cells help conserve water? When [blank_start]water[blank_end] is being lost faster than it can be replenished, the [blank_start]guard[blank_end] cells lose [blank_start]turgor[blank_end] pressure and close the [blank_start]stomata[blank_end]. This reduces the rate of [blank_start]transpiration[blank_end] and water loss.

Why is the concept of the "simple cell" not valid? A single cell is like a tiny self-contained [blank_start]city[blank_end] with its own [blank_start]power[blank_end] plants, chemical factories, food [blank_start]warehouses[blank_end], [blank_start]waste[blank_end] disposal facilities, and [blank_start]transportation[blank_end] networks, all directed automatically by programs in the cell's [blank_start]control[blank_end] center.

Explain why a leaf would not function correctly without veins. Veins are needed to [blank_start]transport[blank_end] water and other nutrients to the leaf from the [blank_start]roots[blank_end] and to transport sugars produced in the [blank_start]leaf[blank_end] to the other parts of the plant.
