ATP because its essentially stored energy. All the cell has to do to release the energy is break off a phosphate. ATP is like money in the bank. It's there when cells need energy. Glucose is the preferred molecule to go through the krebs cycle to be made into ATP, but it has to be converted to ATP before its energy can be used. Starch is a macromolecule and has to be broken down into monosaccharides and then converted into ATP, so it's not he most direct source of energy. DNA is the code for telling the cells what proteins to make. It's not a source of energy.  Sorry its long but hope it helps!!

Answer:

root hairs → 1. absorbs water and nutrients from the soil

vascular tissue → 2. consists of xylem and phloem

chloroplast → 3. the site of photosynthesis inside the cell

stem → 4. holds the leaves up high into the sunlight

leaf → 5. acts like an umbrella to absorb light  

terminal bud → 6. the growing part of the stem

taproot → 7. roots that reach deep into the ground

Explanation:

I have been able to match each term to its correct description.

From the above, we will discover that these are parts of a plant. These parts of the plant enable the plant to carry out photosynthesis and to exist.

The root hairs of the plant absorbs water and nutrients from the soil. When such are absorbed, the vascular tissues help to transport them.

The vascular tissue consists of the xylem and phloem. They  transport fluid and nutrients inside the plant. The vascular tissue is associated with two meristems which are the vascular cambium and the cork cambium. It is at the chloroplast that photosynthesis occur; where light energy is converted to chemical energy.

The stem holds the leaves firmly in order to project it to the sunlight. The leaf absorb sunlight which is needed for photosynthesis. The terminal bud is actually the part of the stem that is growing out. Taproot reach deep down the ground in search of water for the plant.

How do the eyespot and the chloroplasts work together to help euglena survive?
zheka24 [161]
The eye spot and the chloroplasts work together to help the euglena survive because the eye spot senses the light and the dark. Since euglena need to do photosynthesis in which uses light energy to make usable energy, to get food, the eye spot will tell the euglena where to move in order for it to be able to do photosynthesis.
