Which types of plant cells must receive glucose from other plant cells?
levacccp [35]

Answer:

While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. They need mitochondria for this.

In particular, at night when there is no light, plants undergo cellular respiration since there is no sunlight to photosynthesize.

They do, however, produce far more sugar and oxygen through photosynthesis than they use up in respiration.

List the steps of steroid hormone action.
Rina8888 [55]
Steroid hormones easily diffuse through the cell membrane. The hormone binds to its receptor in the cytosol, forming a receptor–hormone complex. The receptor–hormone complex then enters the nucleus and binds to the target gene on the DNA.

George Beadle concluded that teosinte is the likely ancestor of maize (corn), even though the two plants appear very different.
Oliga [24]

Answer:

Option B

Explanation:

ALL options are as follows -

a. teosinte and maize can produce fertile hybrids.

b. teosinte and maize have similar chromosomes.

c. Both Teosinte and maize have naked, soft kernel.

d. Teosinte and maize can produce fertile hybrids

Solution

Beadle started working on maize genetics since 1962 after joining graduate school at Cornell University.  

During his research he found that the chromosomes of teosinte and maize possess higher similarity and also show signs of intercross ability of the two species and hence confirmed that wild teosinte is an ancestor of domesticated maize.  

He later concluded that there are only 4 to 5 genes that make these two species different from each other rest all is similar.  

Option B is correct

What feature of living things do the terms unicellular and multicellular describe
marysya [2.9K]

Answer:

The term unicellular and multicellular describe how living things are organized.

Explanation:

The number of cells in living things determine how the body organization will be.

Living things are made up of cells in which there are two types of living cells. We have the unicellular and multicellular cells.

The unicellular are made up of one cell (single cell) the unicellular organisms are simple cells which make their functions simple while the multicellular organisms are made up of two or more organisms and their functions are special unlike the unicellular which the functions are simple

Define cell transport
katrin [286]

Cell transport is movement of materials across cell membranes. Cell transport includes passive and active transport. Passive transport does not require energy whereas active transport requires energy to proceed. Passive transport proceeds through diffusion, facilitated diffusion and osmosis. The purpose of the transport proteins is to protect the cell's internal environment and to keep its balance of salts, nutrients, and proteins within a range that keeps the cell and the organism alive.
