accept or reject my hypothesis

What does IV stand for and what is it?

stands for independent variable and it is the variable that u purposefully change to affect an events result

What does DV stand for and what is it?

stands for dependent variable and it is what we measure when we change the DV

What does CV stand for and what is it ?

stands for control variable and it is the variables that are kept the same

what is qualitative data?

describing words

what is quantitative data?

numbers

What are the parts of the cell?

The main parts of a cell include the cell membrane, cytoplasm, nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and ribosomes.

The __________ is the protective outer layer of the cell that regulates what enters and exits.

cell membrane

The __________ is the jelly-like substance inside the cell where organelles are found.

cytoplasm

The __________ contains the genetic material and is often referred to as the control center of the cell.

nucleus

The __________ are known as the powerhouses of the cell, providing energy through respiration.

mitochondria

The __________ is responsible for the transport of proteins and other substances within the cell.

endoplasmic reticulum

The __________ modifies, sorts, and packages proteins for secretion or delivery to other organelles.

Golgi apparatus

The __________ are involved in digesting waste materials and cellular debris.

lysosomes

The __________ are the sites of protein synthesis within the cell.

ribosomes

The __________ is a rigid layer that provides structural support and protection to the plant cell.

cell wall

The __________ contains chlorophyll and is involved in photosynthesis, converting light energy into chemical energy.

chloroplast

The __________ is a large organelle in plant cells that stores water, nutrients, and waste products.

central vacuole
