Magnification
• Total magnification = eye piece x objective
• If the objective lens is 40X and the eyepiece is 10X, what is the total magnification?

Organelles• Mitochondria = makes energy by cellular
respiration• Vacuoles = storage• Chloroplast = make sugar by photosynthesis• Cell membrane = semi permeable• Cell wall = support• Nucleus = control centre• Ribosomes = make proteins• Golgi = packages proteins• Endoplasmic Reticulum = transports proteins

Digestive System
![Page 9: Unit 1 Review Cells and Systems. Microscope Magnification Total magnification = eye piece x objective If the objective lens is 40X and the eyepiece is](https://reader036.vdocuments.site/reader036/viewer/2022062309/56649f595503460f94c7e80b/html5/thumbnails/9.jpg)
Digestion and Absorption of Nutrients
• Mouth – amalayse digests carbohydrates and teeth chew (BOLUS)
• Stomach – gastic juice has pepsin to digest protien and muscles churn (CHYME)
• Small intestine – bile from liver digests fat and enzymes from pancreas digest fat, carbs, and protien
• All nutrients are absorbed by villi in small and large intestine

Question?
• You eat a bite of hamburger. What path does the bolus of food take? How is it digested along the way?
