Key Concepts

Eukaryotic Cells

Eukaryotic cells are characterized by their membrane-bound structures, which include compartments such as the nucleus, mitochondria, and endoplasmic reticulum. This compartmentalization allows for specialized functions within distinct areas of the cell, contributing to increased complexity and regulation of cellular processes.

Prokaryotic Cells

Prokaryotic cells, such as those found in bacteria, lack membrane-bound organelles. Their cellular components are not compartmentalized, which typically results in simpler internal organization and different mechanisms for carrying out the functions necessary for survival.

Membranous Organelles

Membranous organelles are structures within eukaryotic cells that are enclosed by lipid membranes. These organelles, such as the nucleus, endoplasmic reticulum, and mitochondria, provide functional and structural compartments, allowing eukaryotic cells to isolate and efficiently perform various biochemical processes.

Transcript

00:01 All right, for this question, we are going to be discussing the differences or the main difference between two different domains.

00:06 And domains are just a group that we can use to subcategorize a whole host of different organisms.

00:13 And we're going to look at the domain eukary, which implies eukaryotic, which we can't exactly define at this moment time because that'll give away the answer.

00:22 We're from the get -go before we work through things and sort of rationalize our answer for what distinguishes these two different domains.

00:28 That is eukaria and the other which is bacteria and as we can infer this is going to refer to bacterial organisms and life forms.

00:37 So let's look at different traits and try and see if they could apply to both because if one applies to one but not the other, we know that is going to be the distinguishing property.

00:46 So the first one that we can look at is a cell wall, which hopefully we're familiar with a little bit.

00:52 And i'm just going to abbreviate this as cw.

00:54 This is just going to be a harder, rigid, outer boundary.

00:59 To protect or set as a perimeter around a cell.

01:06 And we know that we could see cell walls specifically.

01:09 We're looking at eukaryotic cells in things such as plant cells.

01:13 Many different examples of those.

01:15 Humans, we don't have a cell wall in our cells because we have those animal cells of the cell membrane, but we still have a cell wall.

01:23 And indeed, for bacteria, which are also prokaryotic, which will go into it a little bit here, they also have a cell wall as well.

01:33 So they both have a cell wall, that hard, rigid boundary that a cell has externally.

01:40 So that is correct for both.

01:42 So let's move on to the next one.

01:44 And the next property is going to be dna.

01:47 And dna, deoxyribose nucleic acid, is just going to be sort of the blueprint having the plans of how an organism is going to develop and carry out different functions, right? of course, eukaryotes have that.

02:03 Humans are eukaryotic.

02:04 We have dna and bacteria do, although their form is a little bit different, which we'll get into as we go on here.

02:09 We're all building and alluding towards something that we'll discover and talk about when we talk about the correct answer here, which we're getting towards.

02:17 Then we have flagella, which are essentially tail -like structures.

02:25 And these are generally existing for the purpose of allowing organisms to move, or that is the cells, to move.

02:32 Around in the environment because you can use these flagella to propagate certain kinds of movement, which we don't need to get into.

02:39 And we know that bacteria have these for sure.

02:42 Now, some eukaryotic cells have flagella that we can look into.

02:46 So there are some examples not all have flagella...
