<span> Inside its enclosed nuclear membrane, it contains the majority of the cell's genetic material which this material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.</span>
1. Animals depend on plants to keep them alive is Plants are producers they take energy from the sun, nutrients from the earth, and water to grow and have their flowers, seeds, and berries.
They also release oxygen, which all animals, including humans, need to stay. Animals are consumers and they all depend on plants for survival.
2. carbon dioxide and water reach the chloroplasts in leaves is Basically the roots consume the water and transports it up the xylem, which gets it to the leaves. Carbon dioxide contacts the chloroplasts in the leaves via a stomata
3. Two pieces of evidence that show that plants cannot make their own food without light. When plants lack light, they don't deliver chlorophyll (the green pigment in plants), and plants can turn pale green to yellow to white. Plant stems become “leggy,” meaning stems become long and thin and appear to be advancing toward the source of light.
- The photosynthesis is the only method for synthesizing food. It is commonly believed that about 717.6Kcal energy is required to prepare just 10g of glucose. No energy input no metabolism and therefore no food.
<h3>How are leaves tested for starch?</h3>
The existence of starch in leaves can be tested by the Iodine test. When we remove chlorophyll from the leaf by cooking it in alcohol and then placing two drops of iodine solution, it is a color change to blue indicates the existence of starch.

Answer: 3/4 of the offspring will have a phenotype resembling the parent with the genotype AABBCc.
Explanation:
This is because out of the eight possible chances, six of them have a physically observable trait similar to the AABBCc genotype.
Answer:
The function of segregating the interior of the cell enclosure to the outside is known to occur by the function of the plasma membrane. These molecules comprising the plasma membrane is none other than lipids. Highly enriched hydrophobic tails of lipids interact with other lipids in a typical bilayer arrangement to regulate and control gene expressive Molecular and other crucial ions from moving in.
Land plants are evolved from green algae.
Green algae called charophytes are coolest relatives of land plants.
It is believed that land plants are the most closely related to green algae, more specifically, a group of green algae referred to as charophyceans. Not only do both land plants and green algae produce chlorophyll a and b, but other evidence suggests that there is a relationship as well.
4 key traits that appear in nearly all land plants but are absent in the charophytes.
-Diploid embryos
- The ability to photosynthesize
-Apical meristem
-Walled spores produced in sporangia.
- Multicellular haploid and diploid generations
-Multicellular gametangia
