A carrot would be an example of a ___ system. The apical meristem and new growth in the roots are protected by the _. Stems of _ contain a ring of vascular tissue, which includes the xylem and phloem. Stems thicken to support plants growing taller during _ growth. _ regulate the exchange of gases in the leaves and help maintain homeostasis. The leaves are often broad and flat because they are the main site of _ in a plant. The force that allows water molecules to stick to other water molecules is called _. The process by which plants release water into the air as vapor, while pulling more water upward into the leaves is called ___. Respond to the following based on your reading. Explain, in your own words, the role of cohesion and adhesion in plant transpiration. What are several adaptations that leaves have undergone? Why do leaves have adaptations in different parts of the world? Choose three nutrients and explain how a plant may look if it has a deficiency in those nutrients.

Cohesion describes water molecules sticking together, while adhesion allows them to stick to the sides of the xylem that runs up the plant stem. When water at the top of this chain breaks free and evaporates from the leaf, it pulls on the water molecules behind it. In this way, water molecules are pulled up the plant stem from the roots and into the leaves.

Leaves have adaptations such as broad or narrow widths, rounded or pointy tips, and straight versus many vertices. These adaptations allow different species of plants to optimize water retention and photosynthesis in different climates (in other words, cloudy, sunny, rainy, dry).

Answers will vary based on the three nutrients selected. Here is a model response: Plants can show many different deficiencies based on their nutrients. An iron deficiency will result in yellowing or brittle leaves. A potassium deficiency causes leaves to turn yellow at the edges and phosphate deficiencies cause plants to have darker green than normal leaves.

A carrot would be an example of a taproot .

stomata regulate the exchange of gases in the leaves and help maintain homeostasis.

The leaves are often broad and flat because they are the main site of photosynthesis in a plant.

The force that allows water molecules to stick to other water molecules is called hydrogen bond .

The process by which plants release water into the air as vapor, while pulling more water upward into the leaves is called transpiration.

The role of cohesion and adhesion in plant transpiration ?

Cohesion and adhesion draw water up the xylem. Transpiration draws water from the leaf. Negative water potential draws water into the root hairs. Cohesion and adhesion draw water up the phloem.

Several adaptations that leaves have undergone?

They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out.

Why adaptations of plants in different habitats occur?

Plants adapt or adjust to their surroundings. This helps them to live and grow.

What are the 3 most common nutrient deficiencies in plants?

The nutrients most commonly deficient in plants are phosphorus, nitrogen, and iron.

Nutrient deficiency symptoms occur as yellowing of leaves, interveinal yellowing of leaves, shortened internodes, or abnormal coloration such as red, purple, or bronze leaves.
