Nucleus and Mitochondria

This document elaborates on the structure and functions of the nucleus and mitochondria, essential organelles in eukaryotic cells. The nucleus, surrounded by a double membrane with large pores, regulates cell activity and controls enzymes. In contrast, mitochondria, with their rod-shaped structure and internal folds called cristae, are crucial for energy production and cellular metabolism. The positioning of both organelles varies across species and cell types, highlighting their significance in maintaining cell structure and function.

Presentation Transcript

  1. Nucleus and Mitochondria Drew Melocik, Niko Carranza, Wyatt Friedman

  2. Structure • Nucleus • Double membrane • Four phospholipids layers • Large pores in which materials pass to and from • Mitochondria • rod-shaped structures • made up of phospholipids and proteins • Many different folds on the inside call cristae

  3. Location in the Cell • Nucleus • Depends on what type of species • Sometimes in the middle • Depends on the placement of the vacuole • Mitochondria • Zig-zags through the whole cell • Takes up a decent amount of space

  4. Type of cells • Nucleus • All Eukaryotic cells have a nucleus • Prokaryotic cells do not have a nucleus • Mitochondria • Muscle cells • Photosynthetic cells • Bacterial cells

  5. Functions • Nucleus • Regulates cell activity • Controls present enzymes • Mitochondria • Energy production • Building, breaking down, recycling needed for proper cell structure
