How is a plant cell built?

Biology
1 answer:
Korolek [52]3 years ago
3 0

Answer:

Plant cells are eukaryotic cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae. Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or centrioles, except in the gametes, and a unique method of cell division involving the formation of a cell plate or phragmoplast that separates the new daughter cells.

hope this helps <3

Identify the stages of the cell cycle using the drop-down menus. Label A-E
Ostrovityanka [42]

Picture attached

Answer:

A - G1 phase

B - G2 phase

C - S phase

D - Mitosis

E - Interphase

Explanation:

Interphase is all the parts of the cell cycle excluding mitosis, and encompasses G1, S, and G2 phases. Cells spend most of their lives in interphase

G1 is the first gap phase, where the cell is growing and making checks in preparation for mitosis. During S phase (the synthesis phase), the DNA is replicated. This is so a full copy of the DNA can be passed on to the daughter cells.

During the G2 phase, the final checks are made before the cell undergoes mitosis, which is where the cell divides.

This week, we'll be exploring the process of photosynthesis, including investigating some critical plant components that enable
Tpy6a [65]

1) Carbon dioxide

The carbon atoms present in CO2 are used by the plant in the formation of the organic molecular group (sugar).

2) Chlorophyll

Photosynthetic pigments present in chloroplasts, responsible for absorbing light from wavelengths between blue and yellow and reflecting different shades of green

3) Oxygen

Oxygen is the end product of photosynthesis, the result of the breakdown process of water molecules.

4) Stomata

Stomates have the function of performing gas exchange between the plant and the external environment. This structure is also responsible for the perspiration of the plant.

5) Sunlight

Energy source for the process of transforming light energy into chemical energy

6) Glucose

Final product of photosynthesis. Molecule that will be used by the plant to maintain its vital functions.

7) Water

Oxygen source that will be released as a gas at the end of the process.

Please provide details for this problem. I got 3.24; therefore accept the null hypothesis.
juin [17]

Answer:

See the answer below

Explanation:

The Chi-square (X^2) is calculated by the formula:

X^2 = \frac{(O - E)^2}{E} where O = observed frequency and E = expected frequency

A standard dihybrid cross is expected to give 9:3:3:1 phenotypic ratio.

Phenotype               O                  E                                  X^2

Round yellow          104       9/16 x 160 = 90          \frac{(104 - 90)^2}{90} = 2.18

Round green            27        3/16 x 160 = 30           \frac{(27 - 30)^2}{30} = 0.30

wringled yellow         27        3/16 x 160 = 30           \frac{(27 - 30)^2}{30} = 0.30

wrinkled green          2          1/16 x 160 = 10              \frac{(2 - 10)^2}{10} = 6.40

Total  X^2 value to two decimal places = 9.18

Degree of freedom = (n-1) = 4 -1 = 3

Critical  X^2 value at 95% probabillity level = 7.815

<em>Since the calculated  </em>X^2<em> si more than the critical  </em>X^2<em> value, </em><em>the null hypothesis is rejected. </em>

Some examples of equivalent fractions include:

  1. 3/6 and 2/4 are both equivalents because they are equal to 1/2
  2. 25/50 and 50/100 are both equivalents because they are equal to 1/2, etc

<h3>What is an Equivalent Fraction?</h3>

This refers to the type of fractions that has different denominators and numerators but have the same value when broken down to the smallest terms.

Furthermore, some more examples of equivalent fractions are:

  • 40/80 and 60/120 are both equivalents because they are equal to 1/2
  • 100/200 and 150/300 are both equivalents because they are equal to 1/2

You should also note that equivalent fractions can be found by multiplying the numerator and the denominator by the same number and you would see if your fraction is an equivalent fraction or not.

Please note that your question is unclear, so I gave you a general overview to help you get a better understanding of the concept of equivalent fractions.
