They are molecules with low weights.Their surface charge must be very low. Water,some amino acids, some other chemicals enter this way

Can water enter a cell by active transport?
There are two ways that the molecules (i.e: water) move through the membrane: passive transport and active transport. Active transport requires that the cell use energy that it has obtained from food to move the molecules (or larger particles) through the cell membrane. Passive transport does not require such an energy expenditure, and occurs spontaneously.
Why is active transport of molecules necessary?
To move substances from low to high concentration.
What is the process by which materials enter and leave the cell through the cell membrane?
Either active transport, passive transport, or facilitated diffusion
What is the function of passive transport?
For molecular substances the cell needs such as glucose or proteins to enter the cell.
What is the importance of passive and active transport to the cell?
It is passive because it does not require energy when moving molecules. It is passive because it does not require energy when moving molecules. There is both active and passive transport. If it is going against the concentration gradient it is active transport. If it is not acting against the concentration gradient it is passive transport.

How do transport proteins make make it easier for certain molecules to diffuse across a membrane?
Facilitated diffusion is the diffusion of molecules.across a membrane through transport proteins. Transport proteins make it easier for molecules to enter or exit acell. But the process is still a form of passive transport.
What is the name of the process of how things get in and out of the cell?
The process by which substances enter and exit the cell is called cellular transport. It primarily occurs through two main mechanisms: passive transport, which does not require energy, and active transport, which requires energy expenditure by the cell. Examples of passive transport include diffusion and osmosis, while examples of active transport include endocytosis and exocytosis.

Does glucose enter a cell by active transport?
GLUT1 is a passive protein transport. Glucose with GLUT1 can only be transported from high to low concentration. With the sodium - glucose symporter it's possible to transport glucose from low to high concentration.
How do materials move through the cell membrane in facilitated diffusion?
In facilitated diffusion, materials move through the cell membrane with the help of protein channels or carriers. These proteins create a passageway or binding site for specific molecules or ions to pass through the membrane. The movement is passive and follows the concentration gradient, meaning that molecules move from an area of higher concentration to an area of lower concentration.
How do nutrients first enter a cell?
nutrient are broken down before entering the cell.small parts of nutrients are taken inside a cell be diffusion and passive transport. there is no energy usage this kind of transport. but there are some big molecules that can not enter cell membrane. so there are taken by active transport.(there is a energy usage in active transport).
What cause certain things to enter cell?
Things can enter the cell through various processes, such as osmosis, diffusion and active transport. Passive transport (diffusion/osmosis) occurs because of a difference in concentration across the membrane.
