Week 11.1: Cell Cycle & Mitosis Lab

Please sign in for attendance.

Cell Cycle & Mitosis Lab Day 1

Welcome to Week 11!

• Exam 3 has been posted!

• Assessment Project has also been posted
• Due on Sunday, 11/17 at 11:59pm

• Week 11 assignments are due on Sunday, 11/3 at 11:59pm

Reminders

Mitotic phase(2 subphases)

Interphase(3 subphases)

Two major phases

• Cell cycle - describes how a cell grows, performs its function for an organism, replicates its DNA, and then divides

Cell Cycle

Onion root tip cells under a compound light microscope

When does a cell divide?

• When an organism is growing

• When tissues are damaged and cells need to be replaced

• When older cells need replacing (such as skin cells)

Mitotic Phase

Drawings of onion root tip cells

Consists of 2 subphases:

• Mitosis
• Prophase
• Metaphase
• Anaphase
• Telophase

• Cytokinesis

Mitotic Phase

• Work on Part 1 and 2 during today's class:

• Part 1: Look at the cell cycle pictures around the room

• Part 2: Use your compound light microscope
