Which is NOT connective tissue? Skeletal muscle
What are the 3 types of muscle and where are they found?
Skeletal-attached to bones Cardiac-heart Smooth-digestive system
“Cell skeleton” is made of microtubules, intermediate filaments, and microfilaments is called the __________.
“Cell skeleton” is made of microtubules, intermediate filaments, and microfilaments is called the cytoskeleton.
What is the difference between endocytosis and exocytosis?
Endocytosis=take into the cell Exocytosis=out of the cell
If a cell has a tail the tail is called a _________.
If a cell has a tail the tail is called a flagella.
Facilitated diffusion requires a _______ ________.
Facilitated diffusion requires a protein channel/molecule.
Know the function of each of these organelles/cell structures Centriole Mitochondria Ribosome Lysosome Microtubule Golgi Nucleolus Microvilli
Know the function of mRNA, rRNA, DNA, proteins
List the 3 different types of RNA and their functions ◦ mRNA (Messenger)-carries message containing info for protein synthesis from DNA in nucleus to ribosome ◦ rRNA (ribosomal)-forms ribosomes and coordinates protein synthesis ◦ tRNA (transfer)-transports amino acids to ribosome and recognizes the mRNA codons
Discuss 3 steps of protein synthesis 1. Uncoil DNA 2. Transcription (DNA mRNA) ◦ Genes code for specific proteins ◦ mRNA forms complementary strand with codons that code for specific amino acids 3. Translation (RNA directed synthesis of protein) ◦ mRNA travels to ribosome ◦ Ribosome “reads” codons ◦ Corresponding tRNA brings amino acids ◦ Amino acids bond together to form a protein
Discuss the 6 stages of cell division ◦ Interphase-cell growth, DNA copied ◦ Prophase-Chromosomes are 2 strands of chromatid, held together by centromere. Centrioles move to opposite ends of cells and form mitotic spindle ◦ Metaphase-chromosomes align in middle of cell ◦ Anaphase-centromeres split and chromosomes move toward opposite ends of cells ◦ Telophase-chromosomes reach opposite ends of the cell, uncoil and become chromatin again. Nuclear membrane reforms ◦ Cytokinesis-organelles and cytoplasm split between 2 new cells.
