Answer:

The correct answer will be option D (cell wall).

Explanation:

Robert Hooke is best known for his discovery and identification of small room like structure called "cells" of plants. He discovered cells in 1665 in cork cambium of the plant which is composed of dead cells and appeared like honeycomb cavities.

Since the cells were dead so he was not able to find any cytoplasm in the cells and just observed the cell walls under the microscope. Although he discovered the cell, he was not able to discover the true function of cells.

Thus, cell wall is the correct answer.

State one use made by plant cells of the glucose produced in photosynthesis
erma4kov [3.2K]

Hello!

Glucose produced in photosynthesis is used in plant cells in a process known as cellular respiration. This occurs when glucose combines with oxygen, allowing for the production of a new energy, known as ATP ! (or Adenosine Triphosphate)

Hope this helps.

A friend claims her pet ferret is descended from the wild polecat. You want to learn more about this ferret ancestor. An online
Butoxors [25]
In order to identify the most recent common ancestor of an animal, the physical and genetic makeup of the organisms must be compared. The two organisms must have striking similarities in order to be considered as closely related.

Despite the difference in their size, the domestic ferret has a great resemblance with the features of an Eastern European polecat. In addition, they have the ability to cross-breed with polecats. Therefore, the most recent ancestor of the ferret is the Eastern European polecat.


This took a long time to type cuz I am a slow typer. But I hope I got the answer correct! Hope you have a great day!:)

Oksanka [162]

Answer:

Green algae is divided into chlorophyte and chlorophyte. It possess chlorophyll a and b.

Bryophytes includes the liverworts, mosses and hornworts. It is know tracheaophytes I.e. is not vascular without extensive transport system, it needs water to reproduce sexually. It's Gametophyte is dominant and stomata are absent. (Hornworts possess stomata; it's related to tracheaophytes.

Ferns have vascular tissue, xylem and pholem, stem, root, leaves, dominant sporophyte. It's sporophyte possess rhizomes and fronds plus sporingia aldo called sori. Ferns are seedless vascular plants.

Gymnosperms includes the conifers, cycad e.t.c. It has its ovules resting on a scale. The ovules later develop into the seed. These seeds are naked as there are not enclosed in the chambers.

Angiosperms have flowers and fruits and show diuble fertilization. This is a  huge clade that consists of all flowering plants. Unlike Gymnosperms

They develop enclosed in chambers known as ovaries.

Anatomy<br> Label each of the following structures or processes.
RSB [31]

Answer:

A - DNA

B - mRNA

C - nuclear pore

D - tRNA

E - ribosome

F - rRNA

Explanation:

<em>The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.</em>

The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.
