Specialised Cells: Revision, Examples, and Functions

Specialised Cells and Cellular Differentiation - A comprehensive guide exploring how cells adapt their structure to perform specific functions in both plants and animals, covering key examples of specialised cells and their unique characteristics.

• Cell differentiation occurs when cells modify their structure to perform specific roles
• Plant specialised cells include xylem cells, palisade cells, and root hair cells
• Animal specialised cells include sperm cells, egg cells, and blood cells
• Each specialized cell type has unique structural adaptations for its function
• The process of cellular differentiation enables organisms to develop complex tissues and organs

<p>Specialised cells are cells that have become modified to perform a specific function, through a process called cellular differentiation.

Animal Specialised Cells

This section details specialised animal cells and their unique adaptations. The content focuses on reproductive cells and blood cells, demonstrating how cellular specialization enables complex biological functions.

Definition: The zona pellucida is a protective layer surrounding the egg cell, crucial for fertilization.

Example: Red blood cells lack nuclei to maximize space for hemoglobin, demonstrating cell differentiation and specialisation.

Highlight: White blood cells, particularly neutrophils and lymphocytes, show complex adaptations for immune function.

The section includes detailed information about:

  • Sperm cells with their motile structure and acrosome
  • Egg cells and their protective layers
  • Red blood cells' biconcave shape for oxygen transport
  • White blood cells' role in immune response

Vocabulary: Lysosomes are cellular structures containing digestive enzymes used by white blood cells to destroy pathogens.

I love this app so much, I also use it daily. I recommend Knowunity to everyone!!! I went from a D to an A with it :D

Philip, iOS User

The app is very simple and well designed. So far I have always found everything I was looking for :D

Lena, iOS user

I love this app ❤️ I actually use it every time I study.

Plant Specialised Cells

This section explores the fundamental types of specialised cells in plants and their specific functions. The text details three main types of plant cells and their structural adaptations.

Definition: Cell differentiation is the process where cells modify their structure to perform specific functions.

Example: Xylem cells are hollow to efficiently transport water through plants, demonstrating how structure relates to function.

Highlight: Palisade cells contain numerous chloroplasts specifically for photosynthesis, showing cell differentiation examples.

The section covers:

  • Xylem cells with their hollow structure for water transport
  • Palisade cells rich in chloroplasts for photosynthesis
  • Root hair cells with extensions to maximize nutrient absorption

Vocabulary: Chloroplasts are specialized cell structures where photosynthesis occurs.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Best app on earth! no words because it’s too good

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
