(87 cards)
Smallest unit of life
Cells
With nucleus
Eukaryotic
Without nucleus
Prokaryotic
What are the Cell Theory?
- All living things are composed of one or more cells
- The Cell is the Basic Unit of Life of Structure and Organization in Organism
- All Cells Arise from Pre - existing Cells
Cell Theory
- All living things are composed of one or more cells
Prokaryotes - Unicellular
Eukaryotes - Multicellular
Unicellular - can only manage single cells
Prokaryotes
Multicellular - can manage multiple cells
Eukaryotes
Cell Theory
New cells are formed through a process called?
Cell Division
Cell Theory
this process is essential for growth, repair, and reproduction in living organisms
All Cells Arise from Pre - Existing Cells
A process that results in two genetically identical daughter cells from a single parent cell
Mitosis (Asexual Reproduction)
A specialized form of cell division that produces gametes (sperm and egg cells), reducing the chromosome number by half, ensuring genetic diversity in sexually reproducing organisms
Meiosis (Sexual Reproduction)
What are the 3 Basic Cell Structure?
Nucleus, Cytoplasm, Cell Membrane
Cell Structure and Function
It controls center of the cell, often referred to as the “brain” of the cell
Nucleus
Cell Structure and Function
Inside the nucleus is the ______, where ribosomal RNA (rRNA) is synthesized and combined with proteins to form ribosomes
Nucleolus
Cell Structure and Function
It is known as the plasma membrane, is a selectively permeable barrier that surrounds the cell, controlling the movement of substances in and out of the cell
Cell Membrane
Cell Structure and Function
jelly like substance within the cell that contains all the organelles, excluding the nucleus
Cytoplasm
Cell Structure and Function
“powerhouses” of the cell, responsible for producing energy in the form of ATP
Mitochondria
Cell Structure and Function
a network of membranous tubules and sacs that lacks ribosomes on its surface, distinguishing it from the rough ER
Smooth Endoplasmic Reticulum (SER)
Cell Structure and Function
an extensive network of membranes studded with ribosomes, giving it a rough appearance
Rough Endoplasmic Reticulum (RER)
Cell Structure and Function
the organelles in plant cells responsible for photosynthesis, converting light energy into chemical energy stored in glucose
(this is for plant cells only)
Chloroplast
Cell Structure and Function
a rigid layer that surrounds the cell membrane, providing support and protection
(only in plant cells, fungi, and some protists)
Cell Wall
Cell Structure and Function
membrane-bound organelles containing digestive enzymes
Lysosome
Cell Structure and Function
small, membrane-bound sacs that transport materials within the cell
Vesicles
Cell Structure and Function
the process by which unspecialized cells (stem cells) develop into distinct cell types with specific structures and functions
Cell Specialization
