What is a vascular plant

Plants that have lignified tissues for conducting water, minerals, and photosynthetic.

Why are organs made up of small cells instead of large cells

Organs are made up of small cells instead of large cells to allow the organs to be not easily harmed. This way if one cell dies or is attacked then the organ will not be damaged. If the cell was larger then the organ might not be able to recover.

What is the role of xylem in a vascular plant

Transports water and nutrients upwards

What is the first organ to develop in the embryo

The first organ to develop in the embryo is the heart. In a fetus, there is a brain, but it isn't fully developed and can't understand signals from the nervous system. Therefore the first functional organ would be the heart. But the first thing to start developing in a fetus is the nervous system. ( no that isn't an organ )

Which best describes a difference between prokaryotic cells and eukaryotic cells

Eukaryotic cells contain organelles that are enclosed in membranes

What is the process of water moving from an area of low solute concentration to an area of high solute concentration

Osmosis is the process of water moving from an area of low solute concentration to an area of high solute concentration.

Why are embryonic stem cells useful for medicine

they are pluripotent

|APEX|

They can become more cells than adult stem cells can.

What protein that allows ions to actively transport across

The transport protein allows substances to travel across the cell membrane. The substance is traveling from low concentration to a higher concentration. The process requires energy and is called active transport. The protein is simply called a transport protein.

How is xylem differ from phloem

xylem is found in the roots

What is a factor that determines whether molecule can cross a cell membrane

size/ polarity can be the factors

What would most like happen if green plants where exposed to less sunlight

The plants will tend to grow lanky and weak, while the leaves will turn yellowish.

What is meant by the following statement The cell membrane is said to be fluid.

It moves sideways

A leaf cell has a very low concentration of salt. What would happen to the leaf cell if it were placed in a highly concentrated salt solution

Answer this question…

The cell would lose water, and the membrane would collapse
