The plasma proteins involved in fighting infections are
NeTakaya
Plasma proteins account at least 8% of the plasma, they contribute to osmotic pressure and maintain water balance in blood and tissues, other functions includes transport and enzymatic activities. Plasma proteins include albumin, fibrinogen and globulin (alpha, beta and gamma). Globulin proteins may be used to fight infections such that gamma globulin antibodies are released by the plasma during immune response.

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.
