CELL STRUCTURE

DATE: Monday, October 26, 2015

TIME: 2:00 PM

WEATHER CONDITIONS: At the time of observation, it was approximately 56˚F outside. There was no precipitation during the time of observation, although it was very cloudy and grey throughout the entire day. There was 30.39 in. of atmospheric pressure. The average humidity was 69%. There was 9 mph wind throughout the day.

CHANGES: It seems as if almost overnight the Turkey Oak changed! Almost all of its leaves are now either completely or partially yellow. There are also less dead leaves scattered around the trunk, although that might have to do with the heavier winds that occurred throughout the day of observation.

PLANT VS. ANIMAL CELLS:

• Similarities vs. Differences
• A plant cell is typically larger in size.
• A plant cell cannot change shape, because it is enclosed by a rigid cell wall. An animal cell can and often does change shape because its cell wall is composed of thin, flexible plasma membrane.
• However, the two cell walls are similar because both have plasma membrane.
• A nucleus lies on one side of the plant cell, and it lies in the middle of an animal cell.
• Plant cells contain chloroplasts which perform photosynthesis, and animal cells completely lack chloroplasts.   
• Both the plant and animal cell are Eukaryotes.
• The nuclei of both cell structures contain DNA, which is assembled from chromosomes. 
• Plant cells are capable of making their own food while animal cells cannot. 
• Both have mitochondria, ribosomes, Golgi Apparatus, and vacuole

EUKARYOTIC VS. PROKARYOTIC CELLS:

• Similarities vs. Differences
• Eukaryotes have true nuclei containing DNA whereas prokaryotes do not. 
• The prokaryotes have DNA within the cytoplasm.
• The genetic material in prokaryotes is not membrane-bound.
• Prokaryotes are generally much smaller than eukaryotes.
• Both prokaryotes and eukaryotes contain: DNA, ribosomes, cytoplasms, cell membrane, and flagella. 
• Because they both have DNA/genetic codes to carry out basic functions, both perform many of the same functions in similar fashion.
