Solution:

Chloroplast are necessary for photosynthesis,

Explanation of Solution

LSC TOMBALL BIOLOGY CONNECT ACCESS, Chapter 8, Problem S3.3BYB

Photosynthesis is an important biological process. It’s only used by plants and other microorganisms to convert light energy into chemical energy that can later be released to energy the organisms.

Plastids

The plastids are cell organelles that are found in the plant cells only and some unicellular organisms (Euglena) of uncertain similarity. These can be classified into several types, depending upon the nature of the pigments they contain. Chloroplasts contain chlorophyll pigments, while chromoplasts contain pigments other than chlorophyll. The leucoplasts are devoid of any pigment. However, they have the capacity to develop pigments as and when necessary. Chlorophyll is the green colored pigment present in the chloroplast of the plant cell. It performs the function of trapping light energy and converts into chemical energy.

Different structures of chloroplast:

The chloroplasts are found in the leaves of green plants and are the most common and biologically important plastids. Fungi lack chloroplasts and are, therefore, heterotrophic. The form varies with the species and organisms. It may be ribbon-like, reticulate, cup-like, spiral, discoid, spherical or ovoid. In higher plants, it is generally discoid in shape. The diameter of chloroplast varies from 4-8 mm. It is about 2 mm thick. Most of the algal cells possess a single chloroplast. In higher plants, however, the number varies from 20-40 per cell.

Importance of Chloroplasts:

(i) Chloroplasts are able to trap solar energy and change it into chemical energy. All living organisms use this chemical energy to perform their life activities.

(ii) Chloroplasts fix up carbon dioxide and release oxygen during photosynthesis. This keeps the percentage of two gases balanced in the atmosphere.

(iii) They store starch either temporarily (e.g. in higher plants) or permanently (e.g. in several algae).

Conclusion

The chloroplast is cell organelle and it is equivalent to mitochondria because it possesses DNA, therefore, chloroplast is known as semiautonomous cell organelle. And chloroplasts may change into chromoplast to provide colors to many flowers and fruits to attract animals. Hence, Chloroplast cellular structures are necessary for photosynthesis.

10. Your instructor will give you 2 amino acids during the activity session (video 2-7. A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids using the same colors as in #7. Do not color the bonds in the backbone of each amino acid. B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds in the backbone of each amino acid. C. Position the two amino acids on the page below in an orientation where the two R groups could bond together. Once you are satisfied, staple or tape the amino acids in place and label the bond that you formed between the two R groups. - Polar covalent Bond - Red - Non polar Covalent boND- yellow - Ionic BonD - PINK Hydrogen Bonn - Purple Hydrophobic interaction-green O=C-N H I.

Find the dental formula and enter it in the following format: I3/3 C1/1 P4/4 M2/3 = 42 (this is not the correct number, just the correct format) Please be aware: the upper jaw is intact (all teeth are present). The bottom jaw/mandible is not intact. The front teeth should include 6 total rectangular teeth (3 on each side) and 2 total large triangular teeth (1 on each side).
